SolTerra Communications has gone carbon neutral - 100%. Since 2004 SolTerra has maintained a carbon neutral office by purchasing renewable electricity from the local power utility. Now SolTerra has neutralized it's carbon footprint for both its office and autos by purchasing renewable energy credits through TerraPass. TerraPass invests in renewable energy projects and offsets carbon emissions produced by its customers.
